This document discusses the evolution of storage from traditional appliances to software-defined storage. It notes that many IT decision makers find current storage capabilities inadequate and unable to handle emerging workloads. Traditional appliances face issues like vendor lock-in, lack of flexibility, and high costs. Public cloud storage is more scalable but still has complexity and limitations. The document then introduces software-defined storage as an open solution with standardized platforms that addresses these issues through increased cost efficiency, provisioning speed, and deployment options with less vendor lock-in and skill requirements. It describes Red Hat's portfolio of Ceph and Gluster open source software-defined storage solutions and their target use cases.
